FILE(3type)

✨ FILE(3type) ✨

okay so bestie, gather round, because today we're talking about FILE — the input/output stream type — and honestly? she's the blueprint 💅

---

🎀 NAME 🎀

FILE — the input/output stream, aka the moment your program decides it wants to talk to literally anything 🫶

📚 LIBRARY 📚

Standard C library (libc) — she's been here since forever, no cap.

🌸 SYNOPSIS 🌸

#include <stdio.h>

typedef /* ... */  FILE;

btw that /* ... */ is doing so much heavy lifting. the internals are not your business, bestie, that's the whole point of her. mystery is her brand 🧚

💖 DESCRIPTION 💖

okay so. FILE is an object type used for streams. that's it. that's the whole description. she's the type you hold onto when you're reading from or writing to a stream — files, terminals, pipes, whatever — and you never ever peek inside her. icon behaviour honestly 👑

👑 STANDARDS 👑

• C11
• POSIX.1-2024

so like, standards-approved across the board, periodt ✨

🦋 HISTORY 🦋

• C89
• POSIX.1-1988

she's lowkey a legacy icon. been slaying since C89, fr fr 💜

💅 NOTES 💅

heads up bestie — this header ALSO gives you this type: <wchar.h> 🍓

(the way that <stdio.h> gets all the clout and <wchar.h> is just standing there holding the same type like 🙈 — anyway now you know, iykyk)
